THREAD-GUIDE.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed May 2s, 1913. Serial No. 770,455.

. which the following is a specification.

Thread used in modern textile machinery is subjected to a variety ofvibrations that tend to dislodge the thread from the eye of the threadguide or hook and this results in numerous annoyances.

t is the principal object of the present invention to construct a guidefor thread, yarn and the like which will be much more efiective in itsfunction of retaining thread and of properly guiding the same during allconditions of service.

The above and other objects and the novel features of the invention willbe apparent from the following description, taken in connection with thedrawing, in which- Figure 1 is a side elevation, partly in section,showing one form of the improved thread guide, and Fig. 2 is a sideelevation, partly in section, showing another guide embodying theinvention.

Referring to the drawing, each gulde comprises a stem A and a body Bformed integral with the stem, the guide belng made of any suitablematerial such as glazed porcelain, enameled metal or the like. Eachguide is provided with a socket S which enters the stem at its lowerface and extends part way into the stem and is adapted to receive theend of a drop wire or other suitable support.

The eye which receives the thread and guides the same comprises anirregular opening extending transversely through the body B and has anaperture or enlarged part 5 at its lower end into which the thread firstpasses as it enters the eye through the inclined, restricted inletpassageway 6 which opens into the enlarged portion 5 intermediate theends of the latter.

The upper wall 7 of the passageway-6 is longer than the lower wall 8 andoverhangs the latter at both ends, the downward projeoting end 9 on theexterior of the guide serving as a hook and forming a continuation ofthe passageway 6 with the outer adjacent wall of the guide so as to.assist in threading the guide. The overhanging edge 10 prevents theloose thread from accidentally passing out through the passageway 6,dropping it into the lower part of the enlargement 5 when it dropsdownwardly out of the curved passageway 11.

The curved passageway 11 opens into the aperture or enlarged part 5 andextends substantially vertically of the body portion.

B and opens at its upper end into the side of a second elongatedenlarged part or transverse aperture 13 which has the two thread guidingparts 14 and 15 at its opposite ends, the guiding part 14 being in aboutthe same relation to the passageway 11 that the lower end of the guidingpart 5 1s to the passageway 6. Thetwo apertures 5 and 18 are thusconnected by a comparatively long and narrow curved channel 11. Theupper guiding part 15 is disposed substantially above the verticalpassageway 11 and is separated therefrom by the lip 16 which overhangsthe edge 17 at the inlet of the passageway 11 into the enlargement 13.The lip serves to divide the long aperture 13 into two thread retainingportions Hand 15 which provide supporting ledges for the thread or yarn.The thread, when it is threaded into the guide and tensioned, will passinto the thread retaining portion 15 and contact with the upper wall 18thereof and when slightly slack and vibrating will be prevented fromdropping into the passageway 11, on account of the overhanging lip 16which tends to retain the thread in the portion 15 of the eye orguidesthe slack thread into the portion 14 of the enlargement 13. Onsubsequent tensioning of the thread it will pass through the narrowpassage 19 into the part 15 and again bear against the top wall 18 ofthe latter. A slight depression 20 in the lower wall of the portion 15adjacent the lip 16 will catch and form a hook with the lip 16 toprevent the thread from dropping out of the portion 15 under ordinaryconditions.

The upper portion 15 of the eye shown in Fig. 2 has an angular part 21which, with the lip 23 that overhangs the lip 16, also serves as a hookto prevent the accidental passage of the thread through the passage 19.1

The provision of the curved passageway 11 connecting the apertures orenlargements 5 and 13 and the thread retaining part 15 with the lip '16which cooperates therewith provides a more eflective and reliable hookfor drop lines in use on modern textile machinery, and has the advantageover thread guides now in use that it retains the thread under normalconditions in the portion 15 and rarely, under ordinary conditions ofservice, does the thread escape from the enlargement 18 and through thepassage 11.

What I claim is:

1. A thread guide comprising a body portion having an eye consisting oftwo transverse apertures extending through the body joined by a narrowpassageway one of said apertures having a lip or projection extendinginto the same to divide it into two thread retaining portions.

2. A thread guide comprising a body portion provided with an eyeconsisting of two transverse apertures in the ends of the body portionconnected by a passageway opening into one of said aperturesintermediate the ends of the latter, said last named aperture havingthread supporting portions at opposite sides of the entrance of saidpassageway.

3. A thread guide comprising a body portion having an eye consisting oftwo aper tures extending through the body portion and joined by apassageway extending longitudinally of the guide and opening into theupper aperture intermediate its ends, a lip dividing the upper apertureinto two thread retaining portions, and an inlet slot opening into thelower aperture.

4-. A thread guide having a body portion provided with an eye includinga passageway extending substantially longitudinally of the body portionand opening into an elongated aperture intermediate the ends of theaperture, and a lip extending into the aperture and forming two threadguiding portions of said aperture.

5. A thread guide consisting of a body portion formed integrally with astem which has a socket therein, an eye in the body portion comprising arelatively narrow curved passageway extending longitudinally of the bodyportion and connecting two apertures extending transversely through thebody portion, one of said apertures being elongated, the longitudinalpassageway opening into said elongated aperture intermediate the endsthereof, a lip formed adjacent the point where the longitudinalpassageway opens into the elongated aperture, said lip dividing theelongated aperture into two thread retaining portions, and an inlet slotopening into the other aperture.

In testimony whereof I affix my signature in presence of two witnesses.
